Kuyini i-4,6-DIHYDROXYISOPHTHALIC ACID CAS 19829-74-4?

I-4,6-Dihydroxyisophthalic acid iyinhlanganisela yezinto eziphilayo, eyaziwa nangokuthi i-terephthalic acid (TDA). Iyimpuphu emhlophe ekristalu, encibilikayo emanzini, ku-alcohol kanye ne-ester solvents, futhi ayincibiliki ku-non-polar solvents. I-4,6-Dihydroxyisophthalic acid iyi-asidi ebuthakathaka, futhi iqembu layo le-hydroxyl liyi-acid, elingabamba iqhaza ekuphenduleni kwe-esterification kanye ne-acylation.

Isicelo

I-4, i-6-dihydroxyisophthalic acid iyinto ebalulekile yokusetshenziswa ekukhiqizweni kwezinto ze-polyester polymer, njenge-polyester fiber, ifilimu ye-polyester, upende we-polyester njalo njalo. Ingasetshenziswa futhi njenge-intermediate ekuhlanganisweni kwamadayi, ama-resin, ama-flame retardants namanye amakhemikhali.
